AI Technical Summary

Technical Problem

The uneven distribution of fluid in existing heat exchange devices leads to low heat exchange efficiency and makes it difficult to achieve uniform distribution of fluid in complex phase states.

Method used

Design a heat exchange device comprising a distribution channel and at least two heat exchange channels, employing a centrally symmetrical or rotationally symmetrical partition structure to form a stable negative pressure zone to promote fluid mixing. After entering the premixing chamber through the first fluid inlet, the fluid is fully mixed in the negative pressure zone, thereby improving the uniformity of fluid distribution.

Benefits of technology

By fully mixing within the negative pressure zone, the fluid can be more evenly distributed to the distribution channels, improving heat exchange efficiency and solving the problem of uneven fluid distribution.
